Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LM9036MMX-3.3 are determined by strict equivalence across the following critical parameters:

• Output voltage: 3.3V fixed
• Output current capacity: 50mA
• Input voltage maximum: 40V
• Voltage dropout: 0.40V @ 50mA
• Quiescent current: 20 µA
• PSRR: 60dB (120Hz)
• Operating temperature range: -40°C ~ 125°C
• Package type: 8-VSSOP
• Protection features: Over Temperature, Reverse Polarity, Short Circuit

All substitute parts listed maintain identical electrical specifications and package compatibility with the main part number. Differences exist only in product status, packaging format (Tape & Reel vs. bulk), RoHS compliance level, and automotive qualification where applicable.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the LM9036MMX-3.3. Selection among available alternatives depends on specific application requirements:

LM9036MM-3.3/NOPB is the primary substitute for general-purpose applications. It is active in production, ROHS3 compliant, and available in high volume (20322 pcs). This part is suitable for consumer and industrial applications where automotive qualification is not required.

LM9036QMM-3.3/NOPB and LM9036QMMX-3.3/NOPB are qualified to AEC-Q100 automotive standards and carry ROHS3 compliance. These parts are appropriate for automotive and mission-critical applications requiring automotive-grade components. The QMM variant offers higher inventory availability (20300 pcs) compared to QMMX (1098 pcs).

The original LM9036MMX-3.3 is obsolete and should be replaced in new designs. All substitute parts are manufactured by Texas Instruments and share identical electrical performance specifications.

Frequently Asked Questions (FAQ)

Q: Can LM9036MM-3.3/NOPB directly replace LM9036MMX-3.3 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The primary differences are product status (active vs. obsolete), RoHS compliance level, and packaging format. Pin configuration, electrical specifications, and package dimensions are equivalent.

Q: What is the difference between the standard and automotive-qualified variants?

A: LM9036QMM-3.3/NOPB and LM9036QMMX-3.3/NOPB carry AEC-Q100 automotive qualification, indicating compliance with automotive reliability and quality standards. Non-qualified variants (LM9036MM-3.3/NOPB) are suitable for general industrial and consumer applications. Electrical performance is identical across all variants.

Q: Are all substitute parts ROHS3 compliant?

A: The original LM9036MMX-3.3 is RoHS non-compliant. All three substitute parts (LM9036MM-3.3/NOPB, LM9036QMM-3.3/NOPB, and LM9036QMMX-3.3/NOPB) are ROHS3 compliant.

Q: What packaging formats are available?

A: The original part (LM9036MMX-3.3) is supplied in bulk packaging. All substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.

Q: Which substitute part should be selected for new automotive designs?

A: Either LM9036QMM-3.3/NOPB or LM9036QMMX-3.3/NOPB should be used for automotive applications due to AEC-Q100 qualification. LM9036QMM-3.3/NOPB is recommended due to higher inventory availability.

Q: Are there any electrical performance differences between substitute parts?

A: No. All substitute parts maintain identical electrical specifications including output voltage (3.3V), output current (50mA), voltage dropout (0.40V @ 50mA), quiescent current (20 µA), PSRR (60dB at 120Hz), and operating temperature range (-40°C ~ 125°C).
